Wonderful. So for myself and everyone else in group understanding is this following correct? DSP to ARM messaging works using Debian and the SDK DSP examples loaded on DSP by Linux automatically? Remoteproc loaded the DSP image from Linux and started it? For those that don't care for JTAG debugging or don't own one can use printf debug is available to debug their DSP applications? Anybody wanting to do same can use these DSP examples as a starting point look at source code and modify these examples into TI RTOS examples assuming they are not already using TI RTOS. Be wonderful to know how big the shared memory is and where to increase it but I think that can be left to the learner. Thank you for sharing this.

One has to understand the RTOS support isn't beagle.org and e2e isn't for the Debian kernel I think that's clear to most people except beginners. I agree both this group and e2e are great resources and this group has done a lot to promote learning Linux. There is a gap for learning RTOS especially in colleges. Both operating system have there merits is my message.

You helped me look for the linker command file for the DSP build. The linker is allocating space for the resource table, but I don't see where the server_dsp1 code is statically initializing the table in the RTOS SDK linux build (DRA7XX_linux_elf build for ex02_message). I just need to make sure that the DSP1 build's resource table is getting initialized and retry and see if the remoteproc error goes away on the BB.ORG latest BB-X15 build which I am loading all of the DSP/IPU images (built under TI SDK RTOS) onto. I did notice that the IPU code under the same example DOES appear to be statically initializing it's resource table, so I thought I'd give loading that a try with remoteproc on the latest Debian image for the BB-X15 by deleting the exitsing IPU load on the Debian image, ln -s to it in /lib/firmware, bind it, and look at the dmesg remoteproc traffic. I see something interesting here and hopefully promissing!! Maybe a good intermediate step would be to build the application side of the ex02 linux application natively on the BB-X15 and see if it will pingpong the 14 messages with IPU1 on the Debian build as shown on the TI IPC examples.. This is just a baby step, but it maybe of interest to someone...

I tried starting to port one of the main examples from TI RTOS SDK into the latest Beagleboard-X15 images this weekend. Built the IPC example under the link you posted yesterday. Scp'd server_dsp1.xe66 to the SD card and then linked to it, and attempted to load. It looks like it started to load but then complained that the resource table is not found. I have lots more homework to do.. My plan dejour is to try to see how far I can get with that example on BB Debian and TI SDK Linux. I do plan to develop the DSP application with CCS and JTAG, and deploy it using remoteproc from Linux once it's debugged. Don't know if there are currently any Linux tools for debugging the other cores. But at this point I'm not sure where this will all lead.. But it sounds like there's an appetite within the Beagle community to get this tested and working... My guess is the more applications that can access the other processors on the SOC, the merrier for BB.org and TI..

Also google all of the examples on of PRU applications . My guess is that may also shed some light on how to develop and debug code for the other processors on the Sitara SOC of interest.

I have a lot of questions on how this works, and I will post up when I think I have something worthwhile or relevant.. Also, please post up as you make progress as I imagine there are others wanting guidance on developing applications on the other processors on the SOC and interfacing Linux to them.
